Global Climate Change01:50

Global Climate Change

28.9K
Throughout its ~4.5 billion year history, the Earth has experienced periods of warming and cooling. However, the current drastic increase in global temperatures is well outside of the Earth’s cyclic norms, and evidence for human-caused global climate change is compelling. Paleoclimatology, the study of ancient climate conditions, provides ample evidence for human-caused global climate change by comparing recent conditions with those in the past.

Lung Capacity01:47

Lung Capacity

56.2K
The air in the lungs is measured in volumes and capacities. Lung volume measures reflect the amount of air taken in, released, or left over after a lung function, like a single inhalation. Lung capacity measures are sums of two or more lung volume measures.

Work Done During Volume Change01:17

Work Done During Volume Change

5.1K
In mechanics, work is done on an object when the force acting on it displaces the object. In thermodynamics, work done on a system can be estimated when the system's volume changes during any thermodynamic process.
Consider a gas confined to a cylinder fitted with a movable piston at one end. If the gas expands from volume V1 to volume V2, it exerts a force on the piston, such that the piston moves by a distance dr.
The work done by the gas on the piston can be expressed as

Net Change Theorem01:22

Net Change Theorem

68
The Net Change Theorem is a fundamental principle in calculus that establishes a direct relationship between a function’s rate of change and its accumulated change over an interval. Mathematically, it states that the definite integral of a function's derivative over a given interval [a,b] yields the net change in the original function:This theorem has significant applications in various real-world scenarios, including physics, economics, and engineering. A particularly useful application...

Standard Entropy Change for a Reaction03:00

Standard Entropy Change for a Reaction

24.2K
Entropy is a state function, so the standard entropy change for a chemical reaction (ΔS°rxn) can be calculated from the difference in standard entropy between the products and the reactants.

Le Chatelier's Principle: Changing Temperature02:19

Le Chatelier's Principle: Changing Temperature

35.3K
Consistent with the law of mass action, an equilibrium stressed by a change in concentration will shift to re-establish equilibrium without any change in the value of the equilibrium constant, K. When an equilibrium shifts in response to a temperature change, however, it is re-established with a different relative composition that exhibits a different value for the equilibrium constant.
To understand this phenomenon, consider the elementary reaction:

Area of Science:

  • Oncology
  • Pulmonology
  • Nuclear Medicine

Background:

  • Lung carcinoids, rare neuroendocrine tumors (NETs), comprise 1-2% of lung cancers.
  • Clinical management often follows general lung cancer protocols, not NET-specific guidelines.

Purpose of the Study:

  • To analyze a 12-year real-world experience with lung carcinoids.
  • Identify diagnostic, treatment, and follow-up care gaps in a Comprehensive Cancer Center.

Main Methods:

  • Retrospective observational cohort study of 129 adult patients with lung carcinoids.
  • Data collected: demographics, clinical presentation, imaging (FDG-PET/CT, SSTR-PET/CT), and treatment.
  • Descriptive analysis of collected data.

Main Results:

  • Most patients (65.1%) presented with early-stage disease; 17.1% had stage IV.
  • Surgery was the primary treatment for 78.3% of patients.
  • Heterogeneity noted in diagnostic imaging, with frequent FDG-PET/CT use even in typical carcinoids.

Conclusions:

  • Real-world data reveals diagnostic pathway heterogeneity and non-standardized follow-up for lung carcinoids.
  • Excessive use of FDG-PET/CT in typical carcinoids identified.
  • Need for dedicated multidisciplinary lung-NET boards and reference centers to standardize management.
